Main technical indicators:
Steel hammer mass: 800 ± 2g
Steel hammer drop: 0.2-0.3m

Operation steps:

Cut a 25mm * 200mm reflective film sample, remove a 100mm long anti sticking paper from one end to expose the backing adhesive, and stick it on a 50mm * 200mm aluminum alloy plate, leaving the remaining 100mm to make an adhesive performance sample. Place the reflective film of the sample facing downwards, hang an 800g heavy hammer at the remaining end, and hang it at a 90 degree angle to the surface of the sample. After 5 minutes, measure the length L of the reflective film that has been peeled off.
